METHOD OF SPECTROPHOTOMETRY ANALYSIS OF ASPARCAM FOR DETERMINATION OF POTASSIUM Russian patent published in 2010 - IPC G01N21/78 G01N31/16 G01N33/15 

FIELD: medicine.

SUBSTANCE: at first, total potassium asparaginate and magnesium asparaginate is determined by a spectrophotometric method when measuring optical density of a coloured reaction product of asparaginate-ions and ninhydrin at wave length 568 nm; amount of magnesium asparaginate is determined by chelatometry titration. To calculate amount of potassium asparaginate in preparation Asparcam, the content of magnesium asparaginate is subtracted.

EFFECT: method provides exact results; it is sensitive, easy-to-implement, and profit-proved; it does not require toxic reagents.
